COMBINED TYPE-WRITING AND COMPUTINGMACHINE.

SPECIFICATION formingpart of Letters Patent No. 686,627, dated November12, 1901.

Application filed July 30,1900.

T at whom it may concern.-

Be it known that I, HOLMES MARsHALL, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in a Combined Type-Writingand Computing Machine, of which the following is a full, clear, andexact description, reference being had to the accompanying draw- [0ings.

My invention is for improvements in a combined type-Writer andcomputing-machine of the general style shown in my prior patent, No.575,570, granted to me January 19, 1897,

and my prior application, Serial No. 677,586, filed April 14:, 1898. Theformer of these patents illustrates a computer and a type-writer and aconnection between them having a laterally-movable pl ungencarriagewhich is coupled with the type-writer carriage, whereby the depressionof the numeral-keys of the type-Writer may both print and compute. Mylater patent referred to provides, among other things, means wherebymarks-e. g., a

2 5 period dividing dollars from centsmay be interspersed withoutaffecting the calculation, there being a separate escapement for thecomputer-carriage.

The present invention has several objects,

0 among which may be enumerated, first, the efficient and simplecombining of a separate escapement for the computer-carriage with asystem of plungers carried by such carriage, so that the connectingapparatus may be conveniently applied to an existing computingmachinehaving finger-keys; second, providing such connection between thetypewriter and the intermediate mechanism that the type-writer may beeasily removed; third,

40 providing a disengaging mechanism adapted to be operated by theshift-key of the typewriter, so that the same keys which operate thecomputing-numerals may when the shift key is pressed operate the othertype without varying the computer; fourth, providing means for obviatingthe necessity of very accurate adjustment of the intermediate connectionbetween the type-writer keys and the computing-keys; fifth, providingmeans for Serial No. 25,258. (No model.)

checking the printed result. A sixth specific 5o object of the inventionis to provide an intermediate mechanism adapted to be used with aRemington type-writer and an arithmometer, such as is now on the market,being manufactu red by the American Arithmometer Company of St. Louis.

The invention consists in the means I employ for accomplishing the aboveobjects and the general objects of simplifying and cheapening theconstruction and rendering it more efficient and the means I havedevised of consolidating some of the operations of the typewriter orarithmometcr with operations required in the intermediate connection, ageneral object being to provide an eflicient combined type-writing andcomputing machine made in simple and separable form, whereby thetype-writer may be used alone for the ordinary operations thereof or thecomputer used alone for its ordinary operations, or the two togetherwith my intermediate mechanism for the joint purpose of simultaneouslywriting and computing.

The invention may be conveniently characterized as consisting of thecombinations of elements hereinafter illustrated, and set out in theclaims.

The drawings fully illustrate my combined type-writer andcoinputing-machine,there being shown with sufficient fullness atypewriter of the Remington type, a computingmachine of the arithmometcrtype, and my intermediate connection between them.

Figure 1 is a side elevation of such complete construction. Fig. 2 isasectional side elevation through my intermediate connection and throughthe keyboard of the typewriter and showing also the keyboard of thecomputer. Fig. 3 is a plan of the intermediate mechanism, thetype-writer being re- 0 moved. Fig. 4 is a similar plan with the barsand their operating-levers removed. These three latter figures are onthe same scale, larger than the scale of Fig. 1. Fig. 5 is a frontelevation of the intermediate connec- 5 tion and the lower part of thetype-writer, being on the same scale as Fig. 1. Fig. 6 is a detail inperspective of the bar for disengaging the connection from thetype-writer when the shift-key is used. Fig. 7 is avertical sectionthrough the two bars of the computer-escapement, and Fig. 8 is avertical section on the line 8 8 of Fig. 2. Fig. 9 is a plan of thetype-writer keyboard. Figs. 10 and 11 are diagrams illustrating the twostyles of num eral-type employed, the former showing the face oftype-levers and the latter the printed product.

As stated, the type-writer shown is of the well-known Remington type,consisting of a keyboard-frame A, containing key-levers B,

with keys I), which through suitable links O operate the type-levers.

D represents the top plate of the typewriter, supported by standardsfrom the keyboard-frame, and on this top plate is the carriage E.

F represents the ribbon-roller.

The computer shown, as mentioned, is an arithmometer and may beconsidered as constructed in accordance with Patents Nos. 388,116,388,117, 388,118, and 388,119 to W. D. Burroughs forcalculating-machines. It includes the inclosing casing G of the boxlikeform shown, carrying on its upper surface finger-keys H, arranged inlongitudinal rows of nine keys each. The number of rows depends on thecapacity of the machine, nine being shown. The transverse row nearestthe front are the No. 1 keys, the next row behind (which for convenienceis placed a little higher) are the No. 2 keys, and the row next aboveand behind it the No. 3, and so on. The keys are depressed as the numberis written. Thusif the number to be added were 4081 the following keyswould be depressed: the fourth key back from the front in the fourthlongitudinal row from the right, the third longitudinal row would beskipped, the next to the rear key in the second longitudinal row beingdepressed, and the front key in the row at the extreme right. When suchkeys have been depressed, a pull forward on the operating-lever J causesthe amount to be added onto that previously on the computing mechanismwithin the casing, and at the same time the number is printed on thepaper running over an impressionroller K, carried in the frame I at therear of the machine. A second consecutive pull on the lever J, togetherwith the depression of an additional key H, prints the total on thestrip of paper. Two additional keys H are provided on the keyboard ofthe computer at the side of the main keyboard, one of which is depressedwhen it is desired to duplicate figures already printed and the other ofwhich is used for preventing the addition of a number wrongly writtenand for printing the total by a second pull of the lever J, as stated.

The particular construction of the interior of the arithmometeris notapart of the present invention and is not shown. Any approved suitablecomputing mechanism may be used,

whether the computer prints on its own paper, as shown, or simplydiscloses the added amount, though the additional printed record is inmany cases a desirable feature.

The connecting mechanism between the type-writer and thecomputing-machine will now be described. This mechanism is inclosedwithin a frame in the form of a box M, open at its upper and under sidesand so shaped as to seat on the arithmometer and carry the type-writer.It has a pair of rigid bars m, which rest on the upper surface of thecomputer-frame, supporting the box, while the box carries studs m,projecting upward, which take into the usual openings in the lower endsof the standards of the Remington type-writer provided for the rubberfeet. Slidable upon a pair of rigid rods m extending across the box M,is the computer-carriage N. This carriage preferably consists of thestepped-shape body, as shown, having at each end a sleeve 11 around therod m which sleeves preferably carry near each end thereof threeantifriction-wheels n. This body or carriage N carries nine plungers779, which are adapted to stand over any longitudinal row of keys H inthe computer. These plun gers are provided with heads at their upperends, with protrusive springs a" about their shanks, and with cushionedfeet, consisting ofa rubber projection a provided to allow somedescension of the plunger after the key H has been depressed to itslimit. The escapement for the computer-carriage extends loosely throughan opening n therein and consists of a pair of notched bars P P, the barP having a longitudinal movement with reference to the bar P equal tothe distance between the notches and given a tendency to move toward theleft by a tensile spring 19, embraced within recesses in the bars andsecured one end to one bar and one to the other. The bar P is carried onthe ends of a pair of pivoted levers p, which are connected by thecross-bar 19 This cross bar is pressed upward by engagement on its underside of a lever U, to the other end of which is attached a tensilespring V, adjustable by a nut o, engaging a bar m extending across thebox. The bar 19 is thus continuously given a pressure upward, beingstopped by the set-screw m carried by one of the brackets 777. securedto the box. The bar carries set-screws p (locked by jamnuts 9 which areengaged by operating-levers U U U U, hereinafter described, to give theproper vertical movement to the escapement-bars when any of these leversare depressed. In the normal position of the parts the notches of bothbars P P are engaged bya dog a, carried by the body N. A long helicalspring R is secured at m to the frame, and after passing around pulleysm m, carried by the frame, is connected by a cord or strap Q, whichpasses over pulleys m m to the computer-carriage N, whereby the carriageis given a tendency to move toward the right. The force of thisspringRis greater than the spring 19, wherefore when the arm 23 isdepressed sufficiently to raise the barP out of engagement with the dog11 the bar P moves to the left a distance of one tooth; but when the barP comes down into engagement with the dog and the barP is freedtherefrom the spring R draws the computer-carriage to the right themovement allowed to the bar P. The computer-carriage is drawn back tothe left by a cord or strip Q, secured to its left side and passing overpulleys m carried by the box, and then around the pulley m on theoutside thereof, and finally attached to the lever J for operating thecomputer. Thus when the lever J is drawn forward at the end of anynumber written, asis necessary to print and add that number, thecomputer-carriage is also drawn back to the left, ready to start a newnumber.

Any desired number of longitudinal rows of keys H may be provided,according to the capacity of the computer, the machine shown in thedrawings having nine rows, enabling the computer to add up to anythingless than a thousand million, or when adding dollars and cents up tonine million nine hundred and ninety-nine thousand nine hundred andninety-nine dollars and ninety-nine cents. Most frequently the columnsto be added will not contain any numbers requiring the use of the keysin one or more of the rows at the extreme left, and in these cases it isa saving of time not to draw the computer-carriage to the extreme left,as this requires perhaps several idle escapements to bring the carriageto the first printing position. To provide the above-mentionedadvantage, I form in the web j of the lever J nine holes j into any oneof which the hook g on the forward endof the strap Q may take. Theseholes are so placed that the full movement of the lever J gives thestrap Q just the right pull to move the computer-carriage the amountcorrespond ing to the hole j employed. Thus when the computer-carriageis to be moved each time to its extreme left the hook q takes into theuppermost hole j in the lever J. When no number is to be frequentlywritten larger than nine hundred and ninety-nine cents, for example, thehook q takes into the third hole from the bottom, as shown in Fig. 5.This draws the computer-carriage back simply to the third longitudinalrow of keys II from the right. This is as shown in Fig. 4.

In order that the operator may see just where the computer-carriage is,a pointer is provided in the form of a bar 01 secured to the forward endof the bodyN and projecting out through a depression on in the upperedge of the front of the box M, just beneath the front plate of thekeyboard of the typewriter. A scale m is provided along this edge belowthe depression. In Fig. 5 this scale appears, with a period indicatingthe position between dollars and cents, a comma for separating thousandsfrom hundreds, and a comma for separating millions from thousands, andstraight vertical lines on each side of these points to indicate thenumerals. The pointer shows the machine to be in position to print. inthe units-column of the dollars, which, as stated, is the position ofthe computer-carriage and of the hook q in the lever J in this figureand in Fig. at. A pair of levers O are provided on the inner surface ofeach side of the box which have downwardly and inwardly extending arms0, adapted to take onto the keys I-l, whereby the depression of theforward ends of those levers depresses the keys. The box M thus does notinterfere with performing any of the operations of thecomputing-machine. Directly over the nine plungers n are nine bails S,pivoted to the brackets 977. carried by the box, and these bails areconnected by links T with levers U, pivoted on the rod on and drawndownward by springs V. The various levers on the rod m are separated bythimbles 072 thereon. Each of the levers U has on its side a lip u,formed by turning to the side a portion of the lever, and above theselips are depending arms l/V, pivoted by suitable straps w to thekey-levers B, which print the numerals on the type-writer. The pivotedarms V pass through openings 3 in a bar Y, whereby they are guided on tothe lips n. Thus whenever a numeral-key is depressed the arm W depressesthe lever U, and this depresses the corresponding bail, which depressesthe corresponding plunger, which actuates the corresponding key H of thecomputer. It will be noticed that the arms W, though they project belowthe base-line of the type-writer, are pivoted, as stated, to thekey-levers, so that when the type-writer is removed to do its ordinarywork these arms maybe folded up along the under side of thekey-levers,being there held in any suitable manner. The same is true of the longerdepending arm WV, to be hereinafter described, wherefore the removal ofthe type-writer does not require the removal of these arms, and thetype-writer may be simply lifted off and used for its ordinary workwithout there being any loose parts to be taken care of. The distancebetween the bails S and the heads of the plungers is such that thenatural depression of the linger-key to print will depress the keys Htheir right amount. To obviate the necessity, however, of the finestadjustment, the rubber feet 71- are provided at the base of theplungers, and these feet allow a slight additional movement of thekey-lever B after the key H has been depressed its full amount, so as toallow the type bar to strike with the proper force against the paper onthe typewriter carriage. This is an important feature, as otherwise itmight easily happen that the key H would receive its full depression andstop the movement of the key-lever before the type-bar had struck withthe required force on the paper.

In type-writers of the Remington type two characters are provided oneach key and on each type-bar, the additional character being used byshifting the paper-carriage. In order that such additional charactersshall be used on the numeral-keys without disarranging the computingoperation, I form the guide Y movable instead of stationary and move itwhen the shift-key is depressed to swing the arms WV out of alinementwith the lips "to, whereby the depression of the key-levers operates thetype-writer only. This is accomplished by turning the ends of the bar Ydownward, as at y, and pivoting these arms at 1 to the box M andproviding one of these arms 3 with the forwardly-extending bellcrank arm3 which has a lip 1 standing beneath an arm W, depending from ashiftkey. A spring y, secured to one of the arms y, normally holds thebar Y with the arms W above the lips to. When the shift-key isdepressed, the whole barY is swung forward and all of the arms W arebrought out of alinement with the lips a. A pin y, extending out throughthe boX M, provides means for this shifting of the bar Y independentlyof the type-writer whenever desired. l/Vhen the zero-key of thetype-writer is depressed, it does not operate any of the keys H of thecomputer, but simply prints the O on the type-writer and causes anescapement of the computer-carriage. This is done by the lever Ucorresponding to the levers U, in that it is journaled on the rod m andlies over the escapement-bar p and has a lip beneath the barY, though itis not connected with a bail.

It is sometimes desirable to move the computencarriage without movingthe type-writer carriage or without printing, and this is accomplishedby a finger-key Z on the forward end of the lever U This lever isjournaled on the rod m and operates the escapement, but otherwise doesnot affect the computer and has no influence whatever on the typewriter,though the keyZ is so placed (by reason of a vertical. shank .2,connecting the key with the lever) that the key projects up into thekeyboard of the type-writer and occupies a position as if it were partof that keyboard, being at one end of the keys therein.

The ordinary space-bar b of the type-writer operates the escapement forthe type-writer carriage in the usual manner, but has no influence onthe computer. It is frequently desirable, however, to cause asimultaneous escapement for both the computer and the typewriter, andthis is accomplished by the lever U, pivoted on the rod m and passingover the escapement-bar p and carrying at its forward end the key Z on ashank a, which extends upward from the lever U and then eX- tends acrossthe lever B, to which the escapement-bar b is secured. Thus when thiskey Z is depressed both escapements are operated. It is thus apparentthat the type-writer escapement may be operated alone, thecomputer-escapement alone, or both escapem ents together, according tothe key depressed, while whenever a computing numeral-key is depressedthe same operates to print on the type-writer and will operate tocompute on the computer if the parts are in their normal position, orwill have no eifect on the computer if the bar Y is shifted to bring theupper-case characters on the numeral-keys into action, as heretoforedescribed.

In practice there are many cases where numerals are used which it is notdesired to add--as in dates, quantities, &c.and to obviate the necessityof disconnecting the typewriter and computer whenever such numerals areto be used I provide an extra set of numerals which do not compute, butsimply print on the type-writer. Fig. 9 shows the keyboard of a No. 7Remington machine as adapted for my use. The numeral-keys in the upperrow are those that connect with the computingmachine, while those nearthe right hand of the other rows do not so connect. It is an advantageto have the keys which compute arranged in a single transverse row, asshown, since they may be thus more easily connected with theintermediate connection to the computingmachine and that connectionshifted, as already explained, though otherwise the arrangement of thekeys is optional.

In order that it may be readily determined from an inspection of theprinted matter whether the right characters have been used, I make thecharacters which compute show differently from those which do not. Thisis most easily accomplished by making them of different size or design.I use the term different font as including either. Fig. 10 shows at c cthe type-levers used with the 8 computing-key and the corresponding keywhich does not compute, respectively. The faces of these levers and thetype thereon are shown at c c. From this figure it will be seen that theS and 9 on the noncomputing bar and the 011 the computing-bar are all ofthe same font, while the 8 on this computing-bar is larger. This isfurther illustrated in Fig. 11, the large characters in the upper linebeing type whose keys are connected with the computing-machine and thesmaller characters on the lower line (which it will be seen are of thesame font as the letter-type) are to be used for ordinary writing. Theamount of diiference between the two sizes of fig ure-type isexaggerated for convenience of illustration.

For the convenient distinguishment of the keys on the type-writer adifference in size corresponding to the type is preferably made in thecharacters on the keys, as shown in Fig. 9. Now, for example, a billcould be written and added as follows:

Inspection of the numeral-type in this shows that the computing keyshave only been.

struck in the two amounts to be added and the computation takenfrom theadding-machine is accurate. The footing being printed with thenon-computing type does not disarrange the com pitting-record. Ifcomputing-keys and non-computing keys had been wrongly used, it wouldappear at a glance from the printed result and the proper correctionscould be made.
